图形技术分析的信息含量

尽管图形技术分析在金融市场上被投资者广泛应用，但信息含量的学术研究却很不充分。本文参考Lo等（2000）和Brock等（1992）的研究框架，开辟了检验图形技术分析信息含量的新视角。通过将技术分析所使用的图形进行分解，设计出了一种衡量图形技术分析信息含量的检验途径，并提出了一个基于bootstrap原理的可用于检验各种交易策略的统计检验方法。此外，本文对原有文献模型的参数选择、形态定义等也提出了较大改进。根据本文对于图形技术分析的改进研究方法，我们首次对中国股市1233支A股进行图形技术分析，研究其包含的信息含量，证明恰当的图形技术分析确实可以提供十分显著的信息含量，从而有力地反驳了技术分析无效的观点。     

浅谈标准溶液对样品含量测定的影响

标准溶液是指已知准确浓度的溶液。在仪器分析中，标准溶液是用来测定样品待测组分含量的比较标准液；在容量分析中，标准溶液是通过本身用量及浓度来反映被测物含量的标准液。在进行样品含量测定中，许多分析方法都要使用标准溶液，而标准溶液是要通过标准浓度（mol／L或g／ml）来反映的，标准溶度的准确与否，直接影响对样品测定的结果，因此标准溶液对样品含量的测定有着非常重要的意义。在产品质量检测中，对样品含量进行定量分析，很多方法离不开标准溶液。如在比色分析中，就是将已知溶度的标准溶液配成标准系列，通过标准曲线来计算样品所测成份的含量；在滴定分析中，也是将已知溶度的标准溶液滴加到被测样品中，用适当的指示剂来反映终点，通过标准溶液的用量和其浓度来计算样品所测成份的含量。可见，在样品的含量测定中，标准溶液的准确性将直接影响检测结果。本人在多年的质检工作中对标准溶液的不准确性现总结如下：一、直接配制法配成的标准溶液其浓度误差对分析结果的影响及产生误差的原因。在仪器分析中，如所配制溶液浓度比实际标准值偏高，就会使分析结果值偏低，反之偏高。所造成的主要原因：一是配制标准溶液所用的试剂纯度不符合要求；二是称样不准；三是稀释标准液时出现偏...

气相色谱内标法测定白酒中乙酸乙酯含量研究

气相色谱内标法就是进行一种毛细管气相色谱法的建立，进而对白酒中乙酸乙酯含量进行检测的一种方式。在检测白酒的过程中，因为乙酸乙酯和乙缩醛极性存在极大的相似性，在分离过程中难度较大。基于此，文章主要对白酒乙酸乙酯的概况、气相色谱内标法测定白酒中乙酸乙酯含量的检测方式及检测分析进行了探究，以此为提高白酒中乙酸乙酯含量的准确度提供可靠的保障。     

浅谈电位滴定法测定工业用氢氧化钠中碳酸钠的含量

针对目前酸碱滴定法测定工业用氢氧化钠中碳酸钠的含量比较复杂，用指示剂指示终点比较困难，且对不同产品因其组分不同，某些组分对测定有干扰，为此，笔者对电位滴定法测定工业用氢氧化钠中碳酸钠的含量进行了多年的研究与探讨。多次对同批样品用两种方法同时进行分析测定，发现电位滴定法与酸碱滴定法在测定工业用氢氧化钠中碳酸钠的含量的精确度相当，笔者还发现电位滴定法尤其对不适用指示剂的粗产品也能进行精确分析，便于实现测量的自动化。

Value at Risk in the Suburbs: Eminent Domain and the Geographical Politics of the US Foreclosure Crisis

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.     

Towards a Theory of Serendipity: A Systematic Review and Conceptualization

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.     

Accountability of NGOs in Bangladesh A critical overview

NGOs in Bangladesh have been recognized as effective change agents in the socio-economic arena throughout the world. Their contributions in micro credit, non-formal education and primary health care are widely known. NGOs play a significant role in society. NGO accountability, as a result, has become a critical issue. NGO accountability in Bangladesh has been examined here in relation to patrons, clients and themselves. Of the three relationships only accountability to patrons is in a near satisfactory state. Accountability to clients is handicapped by lack of opportunities of beneficiaries to participate meaningfully in NGO policy making. Accountability to themselves is adversely affected due to the adherence to a strictly hierarchical system and the influence of founding and charismatic NGO leaders.     

Towards an Asian model of human resource management? A comparative analysis of China,Japan and South Korea

There has been much discussion regarding the possible decline and weakening of national systems of human resource management (HRM). Yet, culture and institutions are often cited as the major stumbling blocks to this outcome. Such constraints may dissipate in the analysis, particularly if ‘regional clusters’ are considered where geographic and cultural closeness and ‘openness’ to similar economic pressures exist. In such cases, it might be postulated that convergence in HRM will occur. We argue that China, Japan and South Korea represent such a cluster. This article examines these countries, to see if a degree of convergence is taking place and if it is towards an identifiable ‘Asian’ model of HRM. A model of change is presented that distinguishes between levels of occurrence and acceptance. Details of the development and practice of HRM in each country are then set out. The article ends with a discussion and implications section and a brief conclusion.     

The Creation of the Office for National Statistics

A new Office for National Statistics was created in the United Kingdom in 1996 following a series of developments designed to strengthen the relevance and integrity of statistics. This paper describes these fundamental changes and sets out a blueprint for future progress. It also sets current developments in the United Kingdom in an historical and international context.     

What helps? Women engineers' accounts of staying on

We have considerable understanding of the obstacles that women engineers encounter and the reasons that they leave the field, but we know less about what enables them to remain. Adopting an interpretivist approach, this article examines how a group of British women engineers in two FTSE 100 companies account for “staying on” in their male‐dominated work settings. We delineate four specific forms of help that facilitate women's retention in the field. We argue that exposure to help leads to women developing a habitus that enables them to continue working in engineering. To conclude, we draw on our findings to outline HR practices that will facilitate supportive relationships in the workplace and pave the way towards developing more positive organisational climates.

Supply Chain Strategies in the UK Fashion Industry—The Rhetoric of Partnership and Realities of Power

This paper focuses on the fashion industry, one characterised by issues such as dramatic shifts in the scale and power of major retail buyers in the market, the advent of retailer own brands, and the nature of sourcing and supply chain decisions, issues that are increasingly global in nature. The aim of this research is to explore the nature of relationships between UK high street multiple fashion retailers and their contracted suppliers, many of whom are entrepreneurial firms by most definitions of the term. Four core themes emerge from the literature and provide a framework for the research, namely, power, process, partnership, and people. The research approach was qualitative, and conducted over a period of twelve months. The paper ends with an agenda for future research.
